6 Claims.

This invention relates to improvements in a combination wrench andelevator and particularly to a wrench and elevator to be used in placingrod, pipe or tubing in a well or removing them therefrom and for holdingthe rod, pipe or tubing while coupling or uncoupling thereof is takingplace. The primary object of this invention is to provide for grippingrods or pipe within the length thereof while it is lowered into orraised out of a well.

Another object of this invention is to provide for automaticallygripping pipe or rods while exerting torsional action thereon.

Another object of this invention is to provide a combination wrench andelevator that is simple in construction, easy to operate and inexpensiveto manufacture; and that will handle either pipe, rod or tubing with aslight change made by an easy and simple interchange of parts.

While the drawings illustrate a preferred embodiment of the invention,it is to be understood that in adapting the same to meet specific needsand requirements, the design may be varied and changes made in the minordetails of construction within the scope of the invention as claimedwithout departing from the spirit thereof.

In the accompanying drawings;

Fig. 1 is a verticalsectional view through one form of the inventionshowing a fragmentary portion of pipe disposed Within the pipe grippingdevice;

Fig. 2 is a plan view of the dog as removed from the pipe grippingdevice;

Fig. 3 is a perspective view of the same form of the invention'as shownin Fig. 1;

Fig. i is an elevational view of a toothed member removed from thedevice;

Fig. 5 is a side elevational view partly in section of a slightlymodified form of the invention adapted to be used with tubing having acoupling on an end thereof;

Fig. 6 is a top plan view of the form of the invention as shown in Fig.5, with parts broken away. and shortened;

Fig. 7 is a longitudinal sectional view through a portion of an elevatorbail member showing the manner of locking the coacting parts together;

Fig. 8 is a view similar to Fig. 5 but with the device modified forhandling rods;

Fig. 9 is a top plan view of the invention as shown in Fig. 8;

Fig. 10 is a side elevational view of this form of the invention withparts in section, of the Fig. 11 is a top plan view of the parts asshown in Fig. 10.

With more detailed reference to the drawing, the numeral i designates abody in which various:- pipe and rod gripping devices may be positionedto meet the requirements of the particular joband the particular partsto be handled.

In the form of the invention as shown in Figs. 1-4 a dog 2, havingangularly disposed toothed jaws 3 at one end and a pivotally mountedbifur-- cated member at the opposite end, is pivoted to the body I on anaxis pin 5. An elongated hole 6 is disposed within the dog 2 and has abushing l intermediate the elongated hole 6 and the axispin 5. A loop 8is swiveled on the upper end of bifurcated member i, to which a cablemay be attached for lifting the elevator wrench unit. The toothed jaws 3preferably have the teeth thereof transversely positioned.

Opposite the toothed jaw 3 is a toothed member 9 having longitudinallydisposed teeth, is secured to the body I by cap screws I0.

The body I has an out-turned flange member H for seating the body on thetop of the casing or other suitable foundation.

This form of the invention is adapted to be used in removing tubing froma well or for lowering it thereinto, when it is desired to grip thetubing intermediate the ends thereof and for holding a length of tubingwhile another length of tubing is coupled thereto or uncoupledtherefrom. The outer end portion of the body I has an opening i2therethrough to permit the passing of the tubing therethrough. The dog2, having angularly formed toothed jaws 3 which are adapted to engagethe side of the tubing then by lifting bifurcated member A upward bymeans of a cable attached to loop 8, the pipe P will be urged intobinding relation with jaws 9. Vfhen the pipe P is positioned in thismanner it is held against either downward or rotary movement untilreleased.

An elongated hole 6 is provided in the dog member 2 so that the dog maybe easily loosened from the pipe, as by tapping on the outer end of thejaws 3. The loosening may also be accomplished by lifting the pipeupward after the pressure on the bifurcated member it has been released.

The member 9 having longitudinally disposed teeth, may be made in avariety of sizes and is adapted to be readily inserted and attached tothe body I by means of cap screw H1. Thus different sizes of the member9 may be used to fit the particular size pipe being handled. The teethof the member 9 are longitudinally disposed to prevent the rotation ofthe pipe being handled.

In the form of the invention shown in Figs. -7, provision is made forattaching a bail member, generally designated as I3, to the body I. Thebody I has round projecting lugs I4 near an end thereof which receivethe eyes of the bail I3. The ball member I3 is comprised of parts I5 andI6 having interengaging teeth II, which enables the two parts I5 and I6that compose bail member I3 to be separated to enable the ready removalfrom and installation on a rigid body I without having to distort thebail member, as would be the case in installing or removing a rigid bailmember. The teeth II are held in engagement by a sleeve I8 sleeved overmember I5 and adapted to wedgingly engage member I6. The sleeve I8 isheld in a locked position by a spring pressed bolt I3 which engages in arecess 20 in the sleeve I8. The sleeve I8 will depress spring pressedbolt I9 to unlock the sleeve upon upward movement of the sleeve, whichwill permit separation of bail parts I5 and I6, when the sleeve haspassed above the end of the bail portion I6. The members I5 and I6 haveloops on their lower ends which form the eyes of the bail and which fitover the round projecting lugs I I as described above.

The loops are held in place by means of cap screws 2I which are threadedinto a hole in each of the round lugs I4.

A forked dog 22 is pivoted on bolt 23 and is adapted to engage beneath acollar 25 on pipe 26 to hold the pipe against downward movement. A bar21 passes through the body of the dog 22 and rests in a notch 28 in thebody I to sustain the load of the pipe 26. The bar 2'! also serves as ahand hold for operating the dog 22. An elongated hole 29 is provided indog 22 to permit the dog 22 to readily adjust itself to various sizes ofthe pipe 26.

The round projecting lugs I l may be made integral with the body I, andit is therefore necessary to make the bail generally designated at I3,in two pieces so they can be readily removed when the elevator is beingused for other purposes in which the bail is not required.

In the form of the invention as shown in Figs. 5-7, the pipe may bepositioned within the loop I2 of the body I and the collar set upon thetop of forked dog 22 and the top of body I. The pipe is free to beturned, but any downward movement thereof is arrested. A cable may beattached to bail I3 for raising and lowering the elevator as describedabove.

In the form of the invention as shown in Figs. 8 to 11, the body I andthe bail I3 are utilized substantially in the manner describedheretofore, but a jaw member 3| is fitted into the loop portion I2 ofthe body I and a projection 32 receives a cap screw II] therethrough tohold this jaw member in place. A dog 33 is adapted to fit within anopening 34 in the jaw member 3|, which opening is below the shoulder 35of rod 36. This Holds the rod in a suspended position and againstturning movement while other rods are being connected thereto. The dog33 is pivoted in a manner similar to the manner that the dog 22 ispivoted, and has an operating handle 31 adapted to seat within notch 28.The elongated hole 38 permits a limited movement of the dog 33 so thatit will adjust itself to rods of various sizes.

With the jaws 3| in place in the looped opening I2 of the body I andwith the dog 33 in a 4 raised position, rods with couplings may beraised through the large open part of the elevator until the coupling isreached. The rod is then swung into the squared opening and the doglowered into position as shown in Figs. 8 and 9 to hold the rod againstdownward movement and at the same time the rod is held against turningmovement while connections are made.
